Abstract
The conductivity is calculated in a semiclassical approximation, which corresponds to the limiting case of strong coupling between the electrons and phonons. The σ(E) dependence has a minimum and a maximum. The equations directly give the activation energy for the mobility from the voltage-current curves: they can also be used to estimate the constant for the electron-phonon interaction.
